Can you sign a quantum state?
Gorjan Alagic, Tommaso Gagliardoni, Christian Majenz
Cryptography with quantum states exhibits a number of surprising and counterintuitive features. In a 2002 work, Barnum et al. argue that these features imply that digital signature…
On Quantum Chosen-Ciphertext Attacks and Learning with Errors
Gorjan Alagic, Stacey Jeffery, Maris Ozols +1
Large-scale quantum computing is a significant threat to classical public-key cryptography. In strong "quantum access" security models, numerous symmetric-key cryptosystems are als…
Quantum-secure message authentication via blind-unforgeability
Gorjan Alagic, Christian Majenz, Alexander Russell +1
Formulating and designing authentication of classical messages in the presence of adversaries with quantum query access has been a longstanding challenge, as the familiar classical…
